Construct a vertical herb garden using recycled tin cans. Paint the cans in vibrant colors or leave them as they are for an industrial look. Attach the cans to a wooden frame or wall using screws or hooks. Fill each can with potting soil and plant herbs like basil, thyme, and parsley. This vertical tin can herb garden is a space-saving solution, allowing you to grow a variety of herbs in a small area while adding a unique decorative element to your outdoor space.
